Application filed November 22, 1912. Serial No. 732,947.

To null vii/(mu, i1 wm concern:

Be it known that I, Jot-1N Fnunnionsoiv, a citizen of the United States, and resident of Billion in the-county of Lake State of 111- (liuna. have inventedn. new and useful linproveinent in Bearings tor Cur-Axles, of which the following is o specification.

The object of my invention is to provide u. bearing by which the friction resulting in cut journals and hot boxes is prevented, and he bearings and journals can be preserved from the destructive effects common to those parts of the running supports of a car. v

The manner in which I accomplish my object is described in the following specification and illustrated in the accompanying (ii-owing in wbtich:

l ig;mrc l is u. plan of a bearing box. the clotted lines indicating the bearing within the box. Fig. 2. is a. side elevation of the ports shown in Fig. 1. Fig. 3. is a bottom plan of the parts shown in Fig. 2. Fig. 4 is a plan of the bearing in position on the axle. Fig. 5 is :1 side elevation of both parts of the beoringin position on the axle. the dotted lines indicating the connecting bolts :intl springs. Fig. 6, is an end elevation of the parts shown in Fig. 5. Fig. 7 is a. centrnl section on the line 7 7 Fig. 4.

in the drawings 8 indicates the box the exterior form of which can be made to fit the box holders foiuilliii'gpnit of the'vorious cur trucks in use. 9 indicates the aperture for the common clustguard in use. 10 inclicatcs a. bottom plate peculiar to this box the purpose ot which is hereinafter described.

Forming part of the box, and part of the bottom plate are perforated projections through which bolts 11. extend, by which the plate 10 is reinovobly secured to the box. l. ir-tible in the box 8 is e bearing 12 the uni-Ker part of which is adapted to rest on the axle 13 in the some manner as the ordinary cor bearing. Extending verticatty through the central part of this bear: ing is :1. here i l. In the lower part of this is 21 recess fornung :1. port 15. and a 1?. lnscrtii'ilo in this bore is a piston 18 the lower owl ot which is provided it" "1 pack inp, rings 19. lflxten ling vertically through this piston u passage 20 which curves outward? throu the side of the lower end of themiston i above the packing rings 1.9,

- and registers with the port .15 when the piston is at rest in the bore. The top oil ..k 16 itch". tc(l.to contain melting T111 the passage 20 is enlarged and threaded to receive and hohl u pipe connection 21' the purpose of which is hereafter described. Extending vertically through the bearing 12 are four holes for the passage of bolts 23. lubricating: bearing The central portion of this bearing" recessed longitudh nally asshown st 25 Fig. 7 and thereby ednptetl to contain lubricating material in contact. with the whole length of the journal o t the axle 13. For the purpose of securing and maintaining the adjustment of the beering; 24, springs 26 are provided which are compressed by the nuts 27 on the bolts 23. Access to these nuts is provided tor by the removal of the phite 10 from the box 8.

.Vhen my device is constructed as described and placed in position in the car truck and on the journal of the axle. its operation and use is as tollowsz-The pipe connection 21. is connected up with the air broke pump or with any air pump ,on the trucks, car bottom or in the car. The air pump may be connected with the air brake, or axle so that its motion is automatic or under control of the engineer or motorinan. The compressed eirenters the passege 20, passes through the port 15 into the chamber 28 formed by the bore lat, end of the piston 18, and journal of the axle 13. The air pressure thus applied lifts the piston 18. The limit of the pistons movement being determinecl by the pressure and the cut otl as the opening of the passage 20 is raised above the top of the port 15. As the piston is raised by the air pressure the box 8 is raised together with the arch her (not shown) which rests upon the box. The weight of the car is therebulrtmd 'l'rom'the hearing These bolts are adopted to support a 8 and is sustained on the air which fills the chamber oflwhich the revolving journal of the axle forms the bottom wall.

The on tight connection of the bearing and axle is maintained under the air pres sure by the pznzking ring 1" ml the spring hour-- on a journal, of a bearing adapted to on journal, said bearing bovine; a cylintlricol bore thereth rough one: it port in said bore, a stun. niovnble in suid bore, having it. pessnge thcrethrough adapted to register with said port, a chamber in said bearing formed by said bore, port, piston and journal wherein compressed air can raise said piston in said bore as described.

2. In a device (it the kind described, the

combination with a bearing box and a journal of an axle or shaft extending therethrough, of a bearing contained in said box and resting on said journal, said bearing having a' cylinder bore and-a-port' therein, a piston movable in said bore, said piston having a passage extending from the external end of said piston into said port, and a chamber *formed by said bore, port, journal, and piston, whereby a fluid forced into said chamber lifts said piston, as and for the purpose described.

3. In a device of the kind described, the combination with a bearing box and an axle or shaft extending therethrough, of a bearing supported in said box and resting on said journal or shaft, said bearing having a bore and a port in said bore, a piston movcble-in said bore, said piston having a passage way adapted to communicate with said port and external portion of said piston,

i' means insertible 'in said box adapted -to contain a lubricating substance, an'd ad: justable means connecting said bearing and said means whereby said lubricating material is held in contact with said journal. or shaft asdescribed.

.4. In a device of the kind described, the

combination with a. box having'open ends for the passage ofan axle or shaft therethrough, and an open-bottom for the inser tion of bearing parts therein, a bottom plate and means for removably securing said plate and thereby closing the bottom of said box; of a bearing irsertible in said box adapted to fit and rest upon an axle or shaft extending through said box, said bearing having a central bore therethrough, a port in said bore and circular check adapted to hold a packing ring, a packing ring held in said check adapted tube in contact with an axle "or shaft on which said bearing is placed, a piston in said bore, having a. passage way therethrough adapted to be opened and closed by the movement of said piston in said bore, a lubricating bearing and lubribox, adjustable means adapted to connect hold said parts in contact with an axle or shaft extending therethrough, and means for connecting said piston with a pressure pump whereby air or fluid is forced through said piston and port into a chamber formed by said bore, piston and axle or shaft and JonN rnnnnioxson.
